Bender ISO685-D Insulation monitoring instrument
This device variant ISOMETER® iso685-D features a high-resolution graphic LC display and operating controls for direct operation of the device functions. It cannot be combined with an FP200.
Features
ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems)
Automatic adaptation to the existing system leakage capacitance
Combination of AMPPlusand other profilespecific measurement methods
Two separately adjustable response value ranges of 1 kΩ…10 MΩ
High-resolution graphical LC display
Connection monitoring (monitoring of the measuring lines)
Automatic device self test
Graphical representation of the insulation resistance over time (isoGraph)
History memory with real-time clock (buffer for three days) for storing 1023 alarm messages with date and time
Current or voltage output 0(4)…20 mA, 0…400 μA, 0…10 V, 2…10 V (galvanically separated), which is analogous to the measured insulation value of the system
Freely programmable digital inputs and outputs
Remote setting via the Internet or Intranet (Webserver/Option: COMTRAXX® Gateway)
Worldwide remote diagnosis via the Internet (made available by Bender Service only)
RS-485/BS (Bender sensor bus) for data exchange with other Bender devices
BCOM, Modbus TCP/RTU and web server
Voltage expandable via coupling devices
